Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a snow stopper, and more particularly to a snow stopper that is less deformed by weight, has a strong restoring force, has a simple structure, and is inexpensive.

[0002]

[Problems to be solved by the device]

 Conventionally, this type of snow stopper comprises an arm member 21 formed by bending a plate material as shown in FIG. 7, and a vertical plate-shaped stopper member 22 having a substantially arc shape and a wide width. , A fixed surface portion 23 from the base end side, a convex portion 24 for positioning with roof tiles, a lower flat surface portion 25, an upper flat surface portion 26 elevated from the lower flat surface portion 25, and a tip of the upper flat surface portion 26. And a bent portion 27 formed into a. Further, an oblique member 28 is fixed to the upper flat surface portion 26 of the arm member 21 so as to be inclined upward, and the upper flat surface portion 26 of the arm member 21 supports the stopper member 22 in the form of a vertical plate from below. In addition to fixing it at the bent portion 27, the oblique member 28 and the upper edge portion of the stopper member 22 are brought into contact with each other, and the both are welded by spot welding or the like, which is fixed at two upper and lower positions. Has been. Then, as shown in FIG. 8, by making the snow stopper 30 narrow between the upper and lower roof tiles 29, 29A, the stopper member 22 is substantially at a right angle at the center of the lower roof tile 29. It is fixed so as to form a snowfall and is configured to receive the snow S. In addition, 31 is a crosspiece and 32 is a ground material.

However, the conventional snow stopper 30 has a problem in that the structure is complicated and therefore the cost is high. Further, since the snow stopper 30 fixes the stopper member 22 at the upper and lower two places, the tip end of the arm member 22 rises with a step and becomes parallel to the roof tile 29 surface as the upper flat surface portion 26. However, when a large amount of snow S is received by the stopper member 22, a tensile stress is applied to the arm member 22 due to the weight of the snow S, especially downward gravity (left side in the drawing), and the arm member 22 is bent and formed. 21 tries to stretch into a flat plate. Since this stress is applied to the roof tile 29 by using the positioning convex portion 24 as a fulcrum, the lower flat surface portion 25 is deformed so as to float. If this deformation occurs, the roof tiles 29 and 29A will also be slightly lifted or the roof tile 29 will be damaged. Further, depending on the snow condition, a larger load may be applied. In this case, since the oblique member 28 and the stopper member 22 are spot-welded at two places A and A, the joint strength is not so large. There is also the problem that it is easy to shift here. Further, the snow stopper 30 has a structure in which the arm member 21 extends to approximately the center of the roof tile 29 and the stopper member 22 receives the snow S at approximately the center of the roof tile 29. Therefore, the downward load due to the snow S is applied to almost the center of the tile 29, but the central part of the tile 29 is the weakest part against the load from the upper side, so the amount of snow S is large. In that case, there is a problem in that the roof tile 29 is damaged, such as cracked, and water resistance is impaired.

The present invention has been made for the purpose of solving the above-mentioned problems, and an object thereof is to provide a snow stopper which has a small deformation due to weight and a large restoring force. Another object of the present invention is to provide a snow stopper which has a simple structure and is inexpensive.

[Means for Solving the Problems]

 The snow stopper according to claim 1 of the present invention is a snow stopper having an arm member narrowed between two upper and lower roof tiles and a vertical plate-shaped stopper member fixed to the tip of the arm member. The arm member has a flat portion formed on the proximal end side, an inclined portion formed on the distal end side, and an attachment portion formed on the distal end of the inclined portion. An attachment receiving portion is formed, and by attaching the arm member to the attachment receiving portion at the attachment portion, the arm member is fixed substantially in the middle of the stopper member. By adopting such a configuration, since the stopper member is fixed by one arm member, the structure is simple and the manufacturing can be performed at low cost. Also, since the arm member is fixed approximately in the middle of the stopper member, it is possible to support the vertical plate-shaped stopper member in a well-balanced manner even if it is loaded by snow, etc. It does not cause a decline. Furthermore, since the inclined portion of the metal arm member exerts elastic force, it absorbs the load during snow accumulation and restores when the snow disappears, so the snow stopper itself does not deform.

The snow stopper according to a second aspect of the invention has a grounding portion bent toward the tip side at the lower edge of the vertical plate-shaped stopper member. By adopting such a configuration, the snow is applied to the vertical plate-shaped stopper member from the base end side during snowfall, but the grounding portion formed on the tip end side causes the stopper member to be pushed from the tip end side. Since the instruction is directed toward the base end side, it is possible to withstand a larger snow load.

According to a third aspect of the present invention, in the snow stopper, the arm member has a length extending from the center of the roof tile to the tip side. By adopting such a configuration, since the stopper member is located at the tip end side of the roof tile, the weight of snow applied to the stopper member is applied to the tip end side of the roof tile. Since it has better pressure resistance than the center, the roof tile will not be cracked and the waterproof function will not be impaired.

According to a fourth aspect of the present invention, in the snow stopper, a reinforcing rib is formed on the arm member. By adopting such a structure, the strength of the arm member is improved, so that the deformation of the arm member is prevented, the snow load resistance is improved, and the damage of the roof tile can be reduced.

Further, in the snow stopper according to a fifth aspect of the present invention, a protrusion for positioning the roof tile is formed on the base end side of the flat portion of the arm member, and the inclined portion and the flat portion are inclined. The ratio of the length to the flat portion is 2: 1 or more. This is due to the following reasons. That is, in the case of a roof tile having a convex portion on the base end side, it is necessary to provide a positioning convex portion that can be fitted to this convex portion on the snow stopper, but the snow stopper does not apply a load to the stopper member due to snow accumulation. In this case, a tensile stress is applied to the arm member, and a stress for making the inclined portion and the flat portion into a flat plate shape is generated. In the case of the snow stopper having the positioning protrusions as described above, this stress is applied by using the positioning protrusions as a fulcrum, so that the inclined portion is pressed downward and the flat portion is pressed upward. As a result, the flat part is likely to float above the roof tile surface. Therefore, in the present invention, since the ratio of the length to the inclined portion and the flat portion is set to be 2: 1 or more, when the stopper members having the same height are used, the flat portion and the inclined portion are inclined. Since the angle formed between the flat portion and the flat portion is small, the stress that tends to lift the flat portion can be reduced. In addition, since the flat plate itself is short, the amount of uplift when flexed is also small. As a result, it is possible to prevent the snow stopper from being deformed and thus prevent the roof tiles from being damaged.

[Embodiment of device]

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The snow stopper 1 of the first embodiment has an arm member 2 made of a metal such as stainless steel or steel and having a flat plate long plate shape, and a wide vertical plate shape fixed to the tip of the arm member 2 on the eaves side. It consists of a stopper member 3. The arm member 2 has a fixed surface portion 4 having holes 4A, 4A for fixing to the base material 13 from the base end side which is the ridge side, and a step portion 5A rising from the fixed surface portion 4 to raise the roof tile 14 , A flat surface portion 5 which is a flat portion having a long hole 5B for fixing together with 14A, and an inclined surface portion 6 which is an inclined portion formed at the tip of the flat surface portion 5, and the inclined surface portion 6 has an upper side at the tip portion. The mounting portion 7 is formed by being bent. A reinforcing rib 8 is formed from the tip end side of the flat surface portion 5 of the arm member 2 to the inclined surface portion 6. The length of the arm member 2 is such that it extends from the center of the roof tile 14 to the eaves side (tip side) when the arm member 2 is mounted between the roof tiles 14 and 14A and attached to the base material 13. . Further, the stopper member 3 is a wide vertical plate body having an arched upper edge portion, and a slit 9A is formed in the lateral direction and a rectangular recessed portion 9B is formed in a substantially central portion thereof. The receiving part 9 is bent toward the eaves at its lower end to form a grounding part 10 against the upper surface of the roof tile 14, while the upper end is bent toward the ridge to form a snow retaining part 11. Has become. Then, the mounting portion 7 of the arm member 2 is inserted from the slit 9A of the mounting receiving portion 9 to fit the mounting portion 7 into the recess 9B, and a fastener such as a stud so as to penetrate the mounting portion 7 and the recess 9B. By fixing both by means of 12, the stopper member 3 is fixed to the arm member 2 at a substantially intermediate position.

The snow stopper 1 according to the first embodiment of the present invention is stacked from above so that the step portion 5A is locked to the ridge-side edge of the roof tile 14 located on the eaves side, and the fixed surface portion. 4 is fixed to the base material 13 in the holes 4A and 4A, and is fixed together with the roof tile 14 by a stopper 15 that penetrates the long hole 5B of the flat surface portion 5 to cover the roof tile 14A located on the ridge side from the upper side. As a result, the roof tiles 14 and 14A can be made narrow. Then, this operation may be repeated at a desired installation location. Incidentally, 16 is a crosspiece provided on the base material 13.

The operation of the above configuration will be described.

By receiving the snow S accumulated on the roof tiles 14 and 14A by the stopper member 3 of the snow stopper 1, it is possible to prevent the snow S from falling from the roof. At this time, since the stopper member 3 is fixed to the arm member 2 at a substantially intermediate position, even if the arm member 2 is a single plate member, its load resistance is large, and since it is at the intermediate position, the snow S This makes it possible to support in a well-balanced manner even if a large load is applied. In addition, since the inclined surface portion 6 of the arm member 2 is elastically deformed, it is possible to absorb the load during snowfall, and since it will not be restored and deformed when the snow is gone, the roof tile 14 is not damaged. It is like this. In particular, the weight of the snow S is applied from the ridge side to the eaves side (from the upper side to the lower side), but in the present embodiment, the lower edge of the stopper member 3 has the grounding portion 10 folded to the eaves side. Since the weight of the snow S can be firmly received from the eaves side, it has excellent weight resistance.

Further, as shown in FIG. 2, the length of the arm member 2 extends from the center of the roof tile 14 to the eaves side when the arm member 2 is attached between the roof tiles 14 and 14A and attached to the base material 13. Therefore, since the stopper member 3 is also located on the eaves side of the roof tile 14, even if an excessive weight is applied to the stopper member 3 by the snow S, the eaves side which is the end of the roof tile 14 is pressure resistant. Since the roof tile 14 is excellent, the roof tile 14 is not cracked and the roof tile's original waterproof function is not impaired. Moreover, in the present embodiment, since the reinforcing ribs 8 are formed on the arm member 2, the strength of the arm member 2 is significantly improved as compared with a simple plate-shaped member. Plastic deformation is prevented, the load resistance is improved, and the risk of damage to the roof tile 14 due to deformation is reduced.

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. The snow stopper according to the second embodiment basically has the same configuration as the snow stopper according to the first embodiment described above, and therefore, the same reference numerals are given to the same components and the detailed description thereof is omitted. . In the snow stopper 1 of the second embodiment, the roof tile 14 has the convex portion 14B on the base end side (ridge side), and accordingly, the positioning protrusion is provided on the base end side of the flat surface portion 5 of the arm member 2. The portion 5C is formed. The ratio of the length L1 of the inclined surface portion 6 to the length L2 of the flat surface portion 5 (from the step portion 5A to the tip of the flat surface portion 5) is 2: 1 or more.

The operation of the above configuration will be described.

By receiving the snow S accumulated on the roof tile 14 on the stopper member 3 of the snow stopper 1, it is possible to prevent the snow S from falling from the roof. At this time, the load of the snow S is also applied in the horizontal direction with respect to the surface of the roof tile 14, but the horizontal load exerts a tensile stress on the tip side of the arm member 2. This stress acts as a force to make the inclined surface portion 6 and the flat portion 5 flat. In the snow stopper of the first embodiment, since the shape is a simple shape, this stress is not a problem because it diffuses to the entire arm member, but the convex portion formed on the roof tile 14 as in the second embodiment. In the case of the snow stopper 1 provided with the positioning projection 5C that can be fitted to the 14B, a force is applied with the tip end side of the positioning projection 5C as a fulcrum. Then, the inclined surface portion 6 is pressed downward and the flat surface portion 5 is pressed upward, and as a result, the flat surface portion 5 may be bent so as to float above the roof tile 14 surface as shown by the broken line in FIG. is there. However, in this embodiment, since the ratio of the length L1 of the inclined surface portion 6 to the length L2 of the flat surface portion 5 is set to 2: 1 or more, if the height of the stopper member is the same, The angle between the surface portion 5 and the inclined surface portion 6 is set to be small. Therefore, even if a horizontal component force G1 is generated in the inclined surface portion 6 by the tensile stress, the vertical component force G2 that acts to lift the flat surface portion 5 can be reduced. In addition, since the flat surface portion 5 itself becomes short, even if it is bent, the amount of lifting thereof will be small. Due to these effects, the roof tile 14 is not damaged and its waterproof function is not impaired.

Further, a third embodiment of the present invention will be described with reference to FIG. In the snow stopper of the third embodiment, the roof tile 14 has a slight convex portion 14C on the base end side, and along with this, the flat surface 5 is formed with a positioning convex portion 5D on the base end side. Other than that, it basically has the same structure as the snow stopper of the first embodiment described above.

Thus, even if the roof tile 14 has the convex portion 14C on the base end side, if the height is gentle, the angle of the inclined surface portion 6 is small as in the second embodiment. It is not necessary to do so, and it is possible to have a configuration similar to that of the first embodiment.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. Noh. For example, the stopper member 3 is a wide vertical plate body having an arch-shaped upper edge portion in each of the above-mentioned embodiments, but the stopper member 3 is not limited to this shape, and various types such as bending the vertical plate body itself can be used. It can be shaped. Further, the shape of the arm portion 2, in particular, the length of the flat surface portion 5, the inclined surface portion 6, the positioning convex portions 5C, 5D, etc., varies depending on the roof tile to be applied as in the first to third embodiments described above. It can be used by changing the length.

[Effect of device]

 The snow stopper according to claim 1 of the present invention is a snow stopper having an arm member narrowed between two upper and lower roof tiles and a vertical plate-shaped stopper member fixed to the tip of the arm member. The arm member has a flat portion formed on the proximal end side, an inclined portion formed on the distal end side, and an attachment portion formed on the distal end of the inclined portion. An attachment receiving portion is formed, and by attaching the arm member to the attachment receiving portion at the attachment portion, the arm member is fixed substantially in the middle of the stopper member. Therefore, since the stopper member is fixed by one arm member, the structure is simple and the manufacturing can be performed at low cost. Also, since the arm member is fixed approximately in the middle of the stopper member, it is possible to support the vertical plate-shaped stopper member in a well-balanced manner even if it is loaded by snow, etc. It does not cause a decline. Further, since the inclined portion of the metal arm member exerts elastic force, it absorbs the load during snow accumulation and restores when the snow disappears, so the snow stopper itself does not deform.

The snow stopper according to a second aspect of the invention has a grounding portion bent toward the tip side at the lower edge of the vertical plate-shaped stopper member, so that the vertical plate-shaped stopper is provided during snow accumulation. The par member is loaded with snow from the base end side, but the grounding portion formed on the tip end side points the stopper member from the tip end side to the base end side, so it is possible to withstand a larger snow load. .

In the snow stopper according to claim 3, since the arm member has a length extending from the center of the roof tile to the tip side, the stopper member is located on the tip side of the roof tile. The weight of snow on the topper member will be applied to the tip side of the roof tile, but since the tip side of the roof tile has better pressure resistance than the center, cracks will not occur in the roof tile and the waterproof function will be impaired. There is no.

In the snow stopper according to claim 4, since the reinforcing ribs are formed on the arm member, the strength of the arm member is improved, so that the arm member is prevented from being deformed, and therefore, the resistance is improved. It is possible to improve snow loadability and reduce the risk of roof tile damage.

Further, in the snow stopper according to a fifth aspect of the invention, a convex portion for positioning the roof tile is formed on the base end side of the flat portion of the arm member, and the inclined portion and the flat portion are inclined. Since the ratio of the length of the flat portion to the length of the flat portion is set to 2: 1 or more, the stress for lifting the flat portion can be reduced. Further, since the flat portion itself is short, the amount of lifting itself when it is bent is small.
